Working Breadcrumb Widget (with source)
Hello folks,
Bytanium has a widget for 4.2 (and it does not work in 4.3), but as you know there is still no officially supported breadcrumb widget for Sitefinity 4.3. Here is something I've "compiled" from the forums. Hope this helps someone.
Installation steps:
1) Create a folder in Sitefinity, say "Controls" under the root
2) Add a new item of type WebUserControl and give it a name "Breadcrumb"
3) Remove the automatically created "Breadcrumb.ascx.designer.cs" file
4) Copy/paste the template code to breadcrumb.ascx
5) Copy/paste the codebehind code to breadcrumb.ascx.cs
6) Build (not Rebuild - Thanks Olav)
3) From sitefinity administration, go to Toolboxes section and register it (I have registered in NavigationControlsSection)
Here is the template and the source code (sorry site did not allow me to upload a zip file)
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Breadcrumb.ascx.cs" Inherits="SitefinityWebApp.Controls.Breadcrumb" %><asp:SiteMapPath ID="SiteMapPath1" runat="server" RenderCurrentNodeAsLink="true" > <CurrentNodeTemplate> <asp:Label runat="server" ID="CurrentNodeItem"></asp:Label> </CurrentNodeTemplate></asp:SiteMapPath>using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using System;using System.Collections.Generic;using System.Linq;using Telerik.Sitefinity;//using Telerik.Sitefinity.Abstractions;//using Telerik.Sitefinity.Configuration;//using Telerik.Sitefinity.GenericContent.Model;//using Telerik.Sitefinity.Libraries.Model;//using Telerik.Sitefinity.Model;//using Telerik.Sitefinity.Modules.Pages.Configuration;//using Telerik.Sitefinity.Security.Model;//using Telerik.Sitefinity.Services;//using Telerik.Web.UI;namespace SitefinityWebApp.Controls public partial class Breadcrumb : System.Web.UI.UserControl public System.Web.UI.WebControls.SiteMapPath SiteMapPath1; protected void Page_Load(object sender, EventArgs e) protected override void OnInit(EventArgs e) base.OnInit(e); SiteMapPath1.ItemCreated += new SiteMapNodeItemEventHandler(SiteMapPath1_ItemCreated); SiteMapPath1.SkipLinkText = String.Empty; SiteMapPath1.CssClass = CssClass; [CssClassProperty] public string CssClass get; set; void SiteMapPath1_ItemCreated(object sender, SiteMapNodeItemEventArgs e) if (e.Item.ItemType == SiteMapNodeItemType.PathSeparator) e.Item.CssClass = CssClass + "Separator"; else if (e.Item.ItemType == SiteMapNodeItemType.Current) e.Item.CssClass = CssClass + "Current"; else e.Item.CssClass = CssClass + "Link"; // hide the root node, and it's following path separator if (e.Item.ItemIndex == 0 || (e.Item.ItemIndex == 1 && e.Item.ItemType == SiteMapNodeItemType.PathSeparator)) e.Item.Visible = false; else if (e.Item.ItemType == SiteMapNodeItemType.Current) using (var sf = App.WorkWith()) var pageNode = sf.Page().PageManager.GetPageNode(((Telerik.Sitefinity.Web.PageSiteNode)e.Item.SiteMapNode).Id); var link = e.Item.FindControl("CurrentNodeLink") as HyperLink; if (link != null) link.Text = pageNode.Title.Value; link.NavigateUrl = (e.Item.SiteMapNode).Url.Replace("~/", "/"); else var label = e.Item.FindControl("CurrentNodeItem") as Label; label.Text = pageNode.Title.Value; Hi Murat Eraydin,
Thank you for sharing the code with the community! This will be indeed useful to many people!
Kind regards,

Thanks a lot Murat, for sharing.
A minor comment:
Don't use Rebuild as in step 6. Just Build, the Rebuild/Clean operations result in missing DLLs in the Bin folder. (guess it's just the way Sitefinity is distributed, don't know if we'll ever actually need to rebuild Sitefinity projects.)
I just copied back the missing ones from the empty project of the Sitefinity Manager, all fine.
Cheers,
Olav
Updated the article, thanks ;)
THANK YOU Murat!!
I'm a Sitefinity 3x dev and am working on my first 4x project and did a "where the hell is the breadcrumb control!".
In trying to use your widget, I keep getting the following errors:
Error 37 The type 'SitefinityWebApp.Controls.BreadCrumb' already contains a definition for 'SiteMapPath1'
Error 38 Ambiguity between 'SitefinityWebApp.Controls.BreadCrumb.SiteMapPath1' and 'SitefinityWebApp.Controls.BreadCrumb.SiteMapPath1'
I can change the variable name on the ascx page, but then I get "Object reference not set to instance of object".
Not sure what the problem is here... I've copied your code in entirety, only difference is the name of the directory that I used.
Did you delete the xxxx.designer.cs file described in step #3?
First Off @Murat Thankyou for sharing your code, it was a real time saver,
@Russell, I am not sure if you got it to work yet but i noticed that you said you changed the directory, this would also mean you would have to modify the namespace at the top of the code behind, for example we use the following so you would just have to change the top line of code from Murat's code
namespace SitefinityWebApp.Custom.UserControls
instead of
namespace SitefinityWebApp.Controls
Thank you Murat, it's very useful :)
i did all the steps you stated but the control could not load on the page i wanted to add the widget too. Also why do you need to delete the "Breadcrumb.ascx.designer.cs" file
I'm having the exact same problem as @Russell.
Error - The type 'SitefinityWebApp.Controls.BreadCrumb' already contains a definition for 'SiteMapPath1'
Error - Ambiguity between 'SitefinityWebApp.Controls.BreadCrumb.SiteMapPath1' and 'SitefinityWebApp.Controls.BreadCrumb.SiteMapPath1'
I did the instructions to the exactly as provided. Controls directory same as described. I'm using Visual Web Developer 2010 Express... it did not create a "Breadcrumb.ascx.designer.cs" file.
Can someone please tell me how to get this working?
Hi Bryan (and Russell)
I've not used Visual Web Developer before but if you get that error, you probably have that *.designer.cs file somewhere in your solution. Check if you have a button called "Show All Files" under Solution Explorer window. You can also check if that file exists in the file system (using Explorer)
HTH
Just checked again and it's not there. It did not create one. Not in the file system either.
